Abstract
A method of stabilizing a glass-ceramic body, particularly an aluminosilicate body, for use as a telecommunications component in a humid atmosphere, comprises coating the body with an aqueous solution of an alkali metasilicate, with a solution of a silane that is strongly non-polar with respect to water, or with successive applications of the metasilicate and the silane.
Claims8
A method of stabilizing a glass-ceramic body against irreversible changes in dimension and/or in CTE from exposure to a humid atmosphere, the body having microcracks with walls that extend into the body from its surface to create an internal surface area, the method comprising coating the walls of the microcracks with an aqueous solution of an alkali metasilicate, or with a non-aqueous solution of a silane that is less polar than water, or with successive coatings of the alkali metasilicate and the silane, the coatings blocking access of moisture to the microcrack surfaces.
